Basically, the MP Rupert Lowe has been kicked out of Reform. (There are various allegations/investigations going on, which, in the round, are irrelevant to me, so I'll forgo them.)
The wider business all started a few months ago, when Elon Musk tweeted out that Nigel Farage needed replacing as leader of Reform. This happened in a broader context of the online right criticising Farage for not wanting to hang out with Tommy Robinson. Amidst that flurry there were polls and questions about who should replace Farage (of course, the people wanting him gone had no idea what would come next). Rupert Lowe tended to top these polls. So, since then, we've had this endless online nudging and campaigning for Lowe to become leader, alongside the unrelenting criticism of Farage.
One thing they've been pushing Farage to do is use the term, "Mass Deportations." The term is vague (perhaps deliberately so). On initial hearing it implies that huge numbers of settled people will be sent back, but it can be reconstrued to just mean those here illegally. So it's imprecise and incendiary. I'm trying to play things with a straight bat these days, but obviously these attempts to push Reform into extreme positions and language feel like sabotage.
Anyway, now Lowe has been ejected - and it's come as something of a shock to all the troublemakers.
I think these people thought that with Lowe being an MP and with Reform having just five MPs there was zero chance they'd push him out. Big mistake. They just don't understand that Farage has spent the last twenty years dealing with people trying to misdirect or sabotage his political vehicles. He literally ditched an entire party he'd created (UKIP), because it was so full of troublemakers, and started a new one from scratch. So, yes, it's not ideal booting Lowe out, but it's better to deal with the problem now than to allow it to linger on for months and years.
It's been fun to watch. The agitators are now completely outside the party. (Whether Rupert Lowe himself is a deliberate agitator or not I don't know - he could just be someone with genuine views who's been a useful crowbar for people wanting to undermine Farage.) Either way, the people criticising Farage are now really throwing their toys out of the pram. We've had some right little tantrums.
What happens now will be interesting. They can kick him out of the party, but they can't kick him out of parliament. Personally, I don't think they'll let him back in the party. I suspect the explosive nature of the spat is deliberate to make sure the bridges are fully burnt. I think the people on the other side (when they've calmed down) might want a burying of the hatchet - to get a toe hold once again. However, I think they've been snookered, and all their crying and online outrage will ebb away like all the other online dramas.
